Hi Tobias,
Unfortunately, this is a basic problem in how the beta 1 compiler
processes MXML components that subclass other MXML components. So the
only "workaround", to use the term loosely, is to make sure that a given
MXML component has no other MXML components in its superclass chain.
Not a feasible alternative in any nontrivial situation, obviously... but
FWIW you can make your stripped-down example work by turning
COMP_List.mxml into COMP_List.as:
package com.foo.bar.COMP {
import mx.controls.List;
public class COMP_List extends List {
public function COMP_List() { super(); }
}
}
Alternatively, you can leave COMP_List alone, and make DSHB_List an AS
component in the analogous way ("import COMP.COMP_List; public class
DSHB_List extends COMP_List ..."). In either case, there's a single MXML
component in the class chain, which will avoid the error. (Having an AS
class extend an MXML component is a less well-trodden use-case, but
there's no fundamental rule against it.)
This is definitely fixed in beta2. In the meantime, apologies - it's
definitely something we should have caught before b1 went out the door.

Subject: RE: [flexcoders] Internal compiler error
I know this isn't going to help you at the moment, but I just tested
your code against our latest compiler, and it compiled without any
error.
I'm CC'ing the guy on our team who I suspect fixed the issue, to see if
there are any workarounds to hold you until Beta 2 is out.
Cheers,
